East Richardson Geophysical Survey

The East Richardson electromagnetic and magnetic airborne geophysical survey is located in interior Alaska in the Richardson mining district, about 80 kilometers southeast of Fairbanks. The survey is adjacent to the Richardson geophysical survey. Frequency domain electromagnetic and magnetic data were collected with the DIGHEMV system from September to November 2005. A total of 1758.4 line kilometers were collected covering 629.0 square kilometers. Line spacing was 400 meters (m). Data were collected 30 m above the ground surface from a helicopter towed sensor platform ('bird') on a 30 m long line. The survey was conducted by Fugro Airborne Surveys Corp. and Stevens Exploration Management Corp. and administered by the Alaska Geological & Geophysical Surveys (DGGS).

• GPR 2006-5. Line, grid, and vector data and plot files for the airborne geophysical survey data of parts of the east Richardson, Liscum, and Black Mountain areas, interior Alaska. The data and maps for this publication were initially released as a compilation of three distinct geophysical surveys. The maps and digital data have subsequently been divided into the original acquisition areas: east Richardson GPR 2018-1, Liscum GPR 2018-2, and Black Mountain GPR 2018-3.
